Abstract

The embodiment of the invention provides a method and a device for correcting an inclined text image, a computer readable storage medium and electronic equipment, and relates to the technical field ofcomputers, and the method comprises the steps: carrying out the text detection of a to-be-corrected text image, and obtaining the position information of at least one text region; determining at least two mark point coordinates of the target text area according to the position information of the at least one text area; determining an inclination angle and a direction of the to-be-corrected text image according to a vector formed by the coordinates of the at least two mark points and a vector in a preset direction; and correcting the to-be-corrected text image according to the inclination angle and direction of the to-be-corrected text image. In the method of the embodiment of the invention, after the text detection is carried out on the to-be-corrected text image through a deep learning model, the inclination angle and direction of the to-be-corrected text image are determined according to the obtained mark point coordinates of the text area, the method is suitable for inclined text image correction of multiple scenes, and the processing process is simple, quick and effective.

Description

technical field [0001] The present invention relates to the technical field of computer software, in particular to a method, device, computer-readable storage medium and electronic equipment for correcting oblique text images. Background technique [0002] In the text image obtained by shooting natural scenes containing text, the text in the text image will inevitably appear a certain degree of inclination, which increases the difficulty of optical character recognition (Optical Character Recognition, OCR) for the text image, the text image The tilt correction of OCR is the key link of text image preprocessing using OCR. Simple, fast and effective correction can assist OCR in more accurate and fast recognition, for example, it can serve various documents and card recognition in insurance business scenarios. [0003] To correct the skew of the text image, the tilt angle of the text image must be detected first. In the related technology, when the straight line in the binariz...
